The molecular mass of ozone is 48. But the average molecular mass of air on ground is 29...
So, doesn't the ozone layer have to fall?

And we're not talking about enclosed systems. Powerboats and sailboats have to be specially designed with storage tanks sealed outside to ensure there is no possible way propane can leak into and pool in the cabin.

Us humans are by nature impatient.
The ozone layer is important because it acts as a shield, protecting the Earth and its inhabitants from harmful ultraviolet (UV) radiation from the sun. Without the ozone layer, the Earth's surface would be bombarded with high levels of UV radiation, which can cause skin cancer, damage to plants and animals, and disrupt ecosystems.
Ozone depletion is primarily caused by human activities, specifically the release of ozone-depleting substances (ODS) such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons. These substances are commonly found in refrigerants, aerosol sprays, and fire extinguishers.
The ozone layer doesn't fall because it is constantly replenished by natural processes. When ozone molecules are broken down by UV radiation, they combine with oxygen atoms to form new ozone molecules. This process is known as the ozone-oxygen cycle and helps maintain the ozone layer's stability.
Ozone depletion can lead to a variety of consequences, including increased UV radiation reaching the Earth's surface, which can harm human health, damage crops and marine life, and disrupt the food chain. It can also contribute to climate change by altering atmospheric temperatures and wind patterns.
In 1987, the Montreal Protocol was adopted by the international community to phase out the production and consumption of ozone-depleting substances. As a result, significant progress has been made in reducing the use of ODS and allowing the ozone layer to recover. However, continued efforts are needed to fully restore and protect the ozone layer.
